Want to be able to breathe in outer space or underwater? Easy — just place a fishbowl or a similar object on your head, and you're good to go.
Obviously, this doesn't work in Real Life.
- Garfield wears one of these while pretending to be an astronaut, much to Jon's frustration about his missing goldfish that the fishbowl used to house.
- My Little Pony: Equestria Girls – Magical Movie Night: In "Dance Magic", when Pinkie Pie has an Art Shifted Imagine Spot of the Rainbooms on the moon and mentions them wearing astronaut gear, all it does is add fishbowl helmets with antennas to their normal clothes.
- In A Pail of Air by Fritz Leiber, a lot of survival equipment had to be made out of whatever was available. The EVA suits' headpieces used to be "big double-duty transparent food cans".
- In a skit of The Benny Hill Show, Hill as Fred Scuttle is being interviewed, and brings on little Jackie Wright wearing a giant fishbowl as part of his space uniform.
- The Goodies on their trip to the Moon had a goldfish swimming around inside their helmet. Then Bill's helmet becomes an overinflated balloon helmet when he turns up the oxygen too high.
- In Captain Video, the spacemen's helmets looked like inverted fishbowls.
- In Kingdom of Loathing, a fishbowl is one of three components needed to craft makeshift scuba gear.
- In MDK 2, Professor Hawkins, a scientist who works through MacGyvering all kinds of available items, uses a fishbowl (a real fishbowl — the fish was sent a few minutes earlier to override some underwater controls) and two horseshoe magnets as boots, in order to cross the space between two sections of his ship.
- RuneScape has a quest ("Recipe for Disaster") that has the player turn a glass fishbowl into a diving helmet for an extended dive.
- Super Mario Bros.:
- In Super Mario Sunshine, Mario wears one during the missions "Red Coins in a Bottle", "Eely-Mouth's Dentist" and "The Red Coin Fish". The helmet doesn't allow him to breathe underwater forever, though, it just slows down the Oxygen Meter.
- In Super Paper Mario, Mario and his party need one to be able to breathe in space. Yes, one. Even though there's three characters in Mario's party (at the time), they apparently only need to breathe when they're the active character. It even changes size depending on who's wearing it.
- Inverted in Terraria. Wearing a fishbowl not only doesn't allow you to breathe underwater, but instead drowns you even in land.
- In the Chip 'n Dale Rescue Rangers episode "Out to Launch", Ditzy Genius mouse Gadget Hackwrench constructs a spacesuit from a rubber glove and a glass jar. Plausible, in that Gadget spent less than a minute outside a pressurized spacecraft.
- There's an episode of Family Guy where a black hole is supposedly about to destroy the world, and Mayor West decides to retaliate by attacking space; he dons a jetpack, then dumps a fishbowl and puts it on his head.
- Josie and the Pussycats: Sebastian the cat plunks an actual fishbowl over his head in order to rescue Josie and the Pussycats from prison capsules on the ocean floor. Thanks to Cartoon Physics, this works.
- SpongeBob SquarePants:
- Sandy wears one so that she can survive underwater. Although she does wear a suit, it looks more like a space suit than scuba gear, and as shown in the episode "Pressure", it doesn't really seem to do anything; it's the helmet that matters. When she takes it off to prove a point (and fails), she saves herself by putting a pickle jar on her head.
- Inverted with SpongeBob and Patrick. When they visit Sandy's treedome, they have to wear fishbowl helmets filled with water. Sometimes they don't.
